,Patent ed June 17, 1930 i One object of the invention is to NEWTON H. HORNE, 0F KANSASVCITY, MISSQURI HYDRAULIC PULSATOBL A Application filed November 3, 1928. SerialNo. 316,962.

This invention relates to surgical appliances and more particularly to a pulsator adapted'to be used to cure piles and internal ailments to which women are subject.

arovide a device of this. character whichmay be inserted into the rectum or vaginal passage and may serve as an applicator through the medium of which ointment may be applied to internal membraneswhile, at the same time, the head of the device which is inserted, may be caused to pulsate and thereby massage the muscles in order to strengthen thermuscles and cause internal organs to be returned to their normal position.

Another object ofthe invention is to so form the device that water may be-caus'ed to flow through the head of the device while it is pulsatingand thereby allow the head to be retained at either a higl'r or low temperature, according to whether hot or cold water is used. By this arrangement the device may serve either as a hot or cold pack, according to the requirements of the ailment which being treated.

Another object of the invention is to providea device of this character in which a hot water bottle of a conventional construction may be employed as a main receptacle and therebymakeit unnecessary to provide a special receptacle and, in addition, allowthe receptacle to be used as a hot water bottle for other purposes.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of the im proved pulsator with fragments of its pipe shown in section. I

Figure 2 is an enlarged View of the pulsator shown principally in longitudinal section.

. Figure 3 is an enlarged fragmentary sectional view taken longitudinally througha coupling and associated parts of the device, the view being taken along the line 33 of Figure2. p

The improved pulsator constituting the subject matter of this invention includes a main receptacle 1 which consists of a hot water bottle of a conventional construction and is formed with'the usual internally threaded neck 2 to receive a threaded stopper when used as a water bottle. The pipe '3 of the device may beef any length desired and consists of sections 4 and 5 between which is disposed a bulb 6. At one end, the pipe at is engaged about the neck 7 of a hollow plug 8 of the proper size to be screwed intothe neck 2 of the water bottle and this head 8 is formed with an outstanding annular flange 9 against which is disposed a gasket or washer 10 so that when the threaded end portion 11 is screwed into the neck 2 of the water .bottle, a tight joint will be formed. It will thus be seen that when the head or coupling 8 is screwed into the neck of the water bottle and the water bottle placed upon a bed,table orother support, the water may flow through the couplinginto the pipe.

The bulb 6 hasits end portions internally thickened as shown at 12, to form attaching ends or necks and these end portions of the bulb are connected with the adjacent ends of the pipe sections 4 and 5 by couplings 13.

These couplings are of a duplicate construction and each includes a thickened central portion 14 from which extend necks 15 terminatingin enlarged heads16 which taper outwardly. toward their ends, as shown in Figure 3. The thickened end portions12 of the bulbengage about the couplings between the enlarged intermediate portions 14 and the heads 16 at their inner ends and the adjacent ends of the pipe sections-4 and 5 engage about the outer necks of the couplings and the heads thereof.

' Therefore, the bulb and the pipe sections will be firmly connected and, due to the tight binding engagement of the bulb and pipe sections withthe couplings, there will be no danger of leakage. Check valves 16 are provided in the couplings, one opening inwardly and the other outwardly so that when the bulb is compressed waterwill beforced out of it into: the pipe 5 and asthebulb expands a fresh supply ofwater is-drawn through the pipe 4 tromthe water bottle.

p The applicator or head 17 of the ClGVlGG 1s formedof-soit rubber and has its outer surface roughened by diagonally extending ribslS crossing each other, as shown in Flgure 1, and serving as scrapers as well as deof hard rubber, metal or any other desired rigid material. The tube 21, which is open at both ends, is formed with side openings 22 spaced from each other suitable distances longitudinally of the tube and the outer end portion of the tube is externallythreaded, as shown at 23, so that the protruding end portion of'the tubemay be screwed into an internally threaded coupling ornipple 24 fitted into the end of the pipe section 5. A locking disc or washer 25 is threaded upon the tube'21 and disposed within the head, and from an inspection of Figure 2, it will be seen that when the tube is screwed into the coupling or nipple 24 the perforated end of the head will be firmly gripped between the nipple and the washer 25,.thereby'providing a tight joint and preventing leakage.

In order to permit water which has passed from the receptacle 1 through the pipe 3 into the head 17, to return to the receptacle, there has been provided a return tube indicated in general bythe numeral 26 in Figure 1 of the drawings. Thisreturn tube is a great deal smaller thanthepipe 3-and is formed of sections 27 28 and 29 which extend respectively through the pipe section 4, bulb 6, and pipe section 5. Stems 30 formed of rigid material extend through the coupling 13, and these stems are surrounded by anchors 31 disposed near the ends of the stems. .Each anchor consists of-a strand of resilient wire bent to form a coil which fits tightly about the stem and the end portions of the .wire strands form arms which project radially from the coil. Referringto FigureB, it will be seen that the arms of the anchor at one end of the stem are fitted into openings formed in the head 16. of the coupling whereas the arms of the anchor at the other end of the stem bear against-the outer end of the head of the coupling. By this arrangement the stems will be retained in proper position with respect to the couplings and they will not interfere with free flow of waterthrougli the couplings. ,In additiontheanchors disposed within the couplings serve to limit outward movement of the check valves 16 away from their seats. he ends of the tube section 28are engaged with the ends of the stems which protrude from the inner ends of the couplings 13 and the outer ends of the stems are engaged by the adjacent ends of the tube sections27 and29. It will thusbe seen that the tube sections 27, 28 and 29 will be united and form a continuous passage for water returning to the receptacle. The tube section 27 is of such length that it passes through the head or coupling 8 and into the receptacle 1, whereas the tube section 29 is of slightly less length than the pipe section 5 and, at its outer end, is engaged with a hollow stem 32 which is freely received in the tube 21 of the head 17.

, When the device is in use the water bottle or receptacle 1 may be filled with hot or cold water according to the nature of the ailment to be treated and, if a cold application is desired, the water bottle may be packed in ice so that the water will be kept cold. After the head'17 has been inserted the bulb 6 is successively squeezed and released and as it is compressed and expands, pulsations will be imparted to the water with which the head 17 and the bulb and water pipe have become filled. These pulsations will cause the head 17, which is formed of soft rubber, to expand and contract and the internal muscles about the head will be massaged. As the head contracts, the water is forced through the small tube back into the water bottle. Therefore, a circulation is established. Ointment or other medicine applied to the head and received in the pockets 19 will be applied to the membranes and, therefore, the device may be used both as an applicator for applyingv ointment to internal muscles and as means for massaging the muscles and causing the muscles and organs controlled thereby to assume their natural positions.
